Patented July 28, 1931 J'OHN P. MOGLAUGHLIN, OF CRUGERS, NEW YORK FILTERING DEVICE Application filed February 3, .1930. :Serial No. 425,555.

The invention relates to 'aiiltering device adapted for connection with a fluid conducting line, by means of which the fluid passing through the line may be freed from impuri ties.

- The primary object of the invention is to provide, ina manner as hereinafter set forth, a filtering device of the character aforesaid which may be -effectively cleaned during the active use of the same without the removal of any ofthe parts thereof.

A further objectof the'invention is to pro- Vide a-filtering device having the foregoing characteristics in which is employed a pair of filteringelements respectively mounted on a pair of valve members rotatably mounted within a housing and adapted to be utilized selectively for filtering the fluid passing through theline.

VJith the foregoing and other objects in View, the ,inventionconsists of the novel con- 7 struction, combination and arrangement of parts as hereinafter more particularly d scribed, and asillustrated inlthe accompanying drawings wherein is showman embodiment of the invention, but it is to be understood that the description,anddrawings are tobe takenasillustrative and thatthe invention'is intended to be limited onlyibythescope ofthe claimsihereunto appended. I In the accompanying drawings in which likenumera-ls are employed toidesignate like parts throughout the several views:

' Referring to the drawings in detail, vthe numeral 1 indicates generallya housing which includes a cylindrical body portion 2 openet its ends and having diametrically opposed wall portions adjacent each end inclining a away vfrom theaxis-of the body portion, such wall portions also inclining away from the ends ofthe body portion andrproviding aplurality of pockets in communication therewith.

are designated by the numerals 3, l, 5 and 16, i

and the pockets above describedaredesignaa ed by the numerals ,7, 8 9 and 10. The end portionsofthe body portion 2 vare oftruecy lindrical forms and are designated by the numerals 11 and 12. The inclined Wall portions 3 and a are in alignment longitudinally of thebodyportion andnicrg-e into internally threaded boss 13 whichprovides a coupling for a pipe such as 14. The inclined wall portions 5 and 6 are in alignment longitudinally of thcvbody portion and merge into an-inter, nally threaded boss '15 which providesacounection for a pipe such as 16.

Midway between the ends thereof, the body portion 2 is provided with a ring 17 which is formal integrally with the body portion, and .the inner peripheral face of which is flush with the inner face of the body portion at the sides of the latter. The uppermost segment vof the ring 17 is vdisposed within the pockets 9 and 10,.and the lowermost segment of the ring is disposed within the pockets 7 and 8. The inner pe= .ripheral face of the ring 17 is slightly incl-inedaway from the-axis thereof, from the center of the 13in toward its-ends. Likewise the inner faceo the body portion 2, at the sidesofthe latter, isinclinedrowanLthea-xis of; the body portion, from the ends of the The inclined wall portions above described body portion to the ring. Thus it will be seen that the interior of the body portion is slightly tapered from both ends thereof toward the center. 7

Between the ring 17 and the end portion 11, the body portion 2 is formed in its sides with oppositely disposed, rectangular openings 18 and 19 which are in alignment transversely of the body portion. Between the ring 17 and end portion 12, the body portion 2 is formed with a similar pair of openings 20 and 21 which are in alignment transversely of the body portion.

Supported by the ring 17 and the end portion 11 is a valve member indicated generally by the numeral 22 which includes a flanged disk 23 slidably and rotatably mounted within the end portion 11. The disk 23 is formed centrally thereof with an outwardly extending, hollow stud 24 which projects beyond the outer end of the end portion 11 in spaced, concentric relation thereto. The inner face of the stud 24 is of poly onal contour to provide a receiving socket 25 for a suitable tool for rotating the valve member 22. i i

Formed integrally with the disk 23 are a pair of oppositely disposed, spaced, arcuate plates 25, the inner ends of which are formed integrallywith a fiangeddisk 26 slidably and rotatably niountedwithin the ring 17 The outer faces ofthe plates 25 slightly con- Verge in a direction toward their inner ends to conform in contour with the tapered inner face of the body portion 2 from the end portion 11 thereof to the ring 17. The flange of the disk 26 is normally maintained in abutment with a pair .of oppositely disposed stops 27 projecting from the inner face of the ring 17 by means of a coiled spring 28 which encircles the stud 24. The respective ends of the springs 28 bear against the outer face of the flanged disk-23 and the inner face of a flange 29 formed on an annulus 30 which is in threaded engagement with the end portion 11. The flange 29 extends toward the stud 24 with the free edge thereof terminating adjacent the stud.

Extending between the disks 23 and 26, and having its ends seating in and secured thereto, is a filtering screen 31 which is substantially in the form of a cylinder having an open side. Longitudinal marginal por- Lions of the screen 31, at the openside of the J latter, are angularly offset and extend across and are secured to opposing longitudinal edge faces at one side of the opposing plates 25. The offset edge portions of the screen 31 are indicatedat The screen 31 is eccen trically disposed with respect to the plates 25 with the maximum space between the screen and plates located diametrically oppositethe open side of the screen.

' Supp rted by the ring 17 and the end portion '12 of the'body portion 2 is a Valve mom-- ber 33, the construction of which is identical with that of valve member 22, and therefore of the screen is arranged at the opening 20 whereby only one thickness of the wall of the screen is interposed between the openings 20 and21'.

The valve member 22 is adjusted with respect to the housing in a manner to close the openings 18 and 19 by means of the plates 25, and to establish communication between the pockets 7 and 9 between the plates 25. The open side of the screen 31 is arranged atthe pocket 7' whereby only one thickness of the wall of the screen is interposed between the pockets 7 and 9. In the arrangement illustrated, the pipe 14 is the inlet pipe, and the pipe 16 is the outlet pipe. With the valve members arranged, as shown, a fluid entering the housing from the pipe 14 will be passed through the pocket 7, filter screen 31, and pocket 9 to the outlet pipe 16, and any inlpurities separated from the fluid by the screen 31 will be deposited within the latter. Owing to the position of the plates 34 of the valve member 33, the sole passage between the pipes 14 and 16 is through the screen 31. With the valve member 33 in the position illustrated, the screen 35 is in proper position to have flushed therefrom any impurities which may have collected therein during its utilization to establish communication between the pockets 8 and '10. Obviously, by directing a fluid stream through the opening 21, any foreign matter within the screen 35 will be washed out of the housing through the opening 20. When it becomes necessary to clean the screen through which the fluid is being filtered, this maybe readily accomplished without cutting OK the flow between the pipes 14 and 16 mere- ]l)y by reversing the position of the valve memers.

It'is thought that the many advantages of a filtering device in accordance with this invention will be readily apparent, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the size, shape and arrangement of parts may be resortedto, so long as such changes fall Within the scope of the invention. as defined in the appended claims.
